The right React Component PropTypes for es6 (Weak) Maps, Sets

Question

I want to force the user to pass an es6 Map object to a React component using PropTypes, like this for example:

static propTypes = {   elementsMap: React.PropTypes.map(React.PropTypes.string, editorPropTypes.element).isRequired, } 

But looks like there is nothing like this in React. (The official documentation).

Answer 1

elementsMap: p.instanceOf(Map).isRequired
